About
About Oshen
Oshen develops compact autonomous surface vessels for persistent ocean observation. Its one-metre C-Star combines wind propulsion, solar-powered electronics, satellite communications and edge processing with configurable acoustic and metocean payloads. Individual vessels can operate for months, while coordinated constellations spread sensing across a wider area than a crewed vessel or fixed buoy.
The company delivers data as a service and also offers platforms for rental or purchase. Publicly described work spans environmental monitoring, weather and ocean-data collection, passive acoustic sensing and maritime security. Oshen reports a 2,000-nautical-mile autonomous passage and more than 200 continuous days on station, alongside Royal Navy-funded North Atlantic trials.

Timeline
Events
- 2026-08-25 - Demonstration - Oceanus12 autonomously deploys two C-Star surface drones
The UK Defence Innovation-backed programme is led by ZeroUSV with Oshen and MarineAI. MarineAI’s GuardianAI autonomy suite coordinated Oceanus12 and the C-Star vehicles with minimal operator input. The two C-Stars were configured for acoustic-data collection; the next planned phase would deploy four vehicles simultaneously.

The Plymouth company plans to grow its fleet from roughly 50 one-metre C-Star autonomous surface vessels toward 150. Capital will support production scale-up and software for coordinating and managing larger robot constellations. C-Star deployments span ocean-data and acoustic sensing, including Royal Navy-funded work connected to North Atlantic hybrid-fleet programmes.
